Very thin lines (0.12 setlinewidth) which trigger the hairline detection when zoomed out. The hairline triggers at a linewidth of < 0.1 device pixels. We may want to tweak this threshold, seeing as I've seen similar issues before, not to mention when rendering thumbnail images of pages.

This appears to be an enhancement request for a feature similar to Acrobat Reader's Enhance Thin Lines option.  

This option (ETL) is not selectable on all versions of Acrobat Reader, e.g. ETL is not selectable in Mac OS X Acrobat 8.3.1, but the ETL function is present by default and therefore a comparison between MuPDF and the Reader appears to demonstrate a bug. 

ETL is selectable in Mac OS X Acrobat 10.1.1. When ETL is disabled, and the zoom in limit for MuPDF is reached, and the Reader is zoomed in to match the zoomed in MuPDF display, the line thickness results are basically the same, at least on a MacBook Pro.
